NAME

Dotiac::DTL::Tag::widthratio - The {% widthratio CURRENTVALUE MAXVALUE CONSTANT %} tag

SYNOPSIS

Template file:

        <img src="bar.png" width="{% widthratio current max 160 %}">

DESCRIPTION

Calculates the ratio of CURRENTVALUE to MAXVALUE and applies this to a CONSTANT.

CURRENTVALUE and MAXVALUES are variables and CONSTANT is a constant number.

This is useful if you want to create a bar for the progress of a multi-page form: CURRENVALUE is the current page, MAXVALUE is the total number of pages a user has to fill out. CONSTANT is then the size of the bar at a 100%, for example 160 for a 160px bar.
